He returned to the mansion from Aulum's room and went out into the yard.

'Mr. Yoda!'
Low level, here we come.

　Emily and Eve, who were in the garden, turned to me at the same time.
　Emily has a troubled look on her face, but Eve is chewing on a carrot with her usual indifferent expression.

　Beyond them was the entrance to a dungeon that led underground.

　If you didn't know anything about it, it would appear to be a hammock built in the garden of a vast mansion.
　But it is unmistakably a dungeon.

　It is the entrance to a dungeon that is more important than anything else in this world and gives birth to everything.

The Dungeon of Erislonium: ......
What?

　Emily is surprised.
　Emily knows that it's the "slain spirit erythronium" because she explained the whole situation to her friends last night after she asked Cell to do so.

''This is it?''
That's what Aulum said. Spirit to spirit sensing, they say it's a sure thing.
I see. ......
So, what's it like inside?
That's .......
I couldn't get in.
What?

　I looked at Emily and Eve in turn as they answered, surprised.

'At first I didn't know what a dungeon was and tried to get in to see what was going on, but it seemed like there was an invisible wall that I couldn't get into at all.'

　Emily said, and headed towards the dungeon entrance.
　She couldn't go on from the entrance, and the movement was like a pantomime, like touching an invisible wall.

'The rabbit didn't make it either,'

　This time, Eve, I say to Emily's side and swing the chop down.
　It's an incredibly slow - I mean almost an all-out chop.
　It sent out a blast and a shockwave, but was blocked by a wall that was as invisible as Emily's.

'You can't get past that much of an attack?
I can feel the rejection.

　A voice from behind me turns me around.

　There are three people there, Nihonium, Meeke, and Sakuya.
　These are the three members of the Nihonium group who have been acting together a lot lately.

　Nihonium appears with them in the position and behavior of a polar wife.

What do you mean by 'rejection'?
'I feel the dungeon, no spirit's will strongly. A rejection that comes from fear.
......

　I didn't go into it any further because I thought I heard a secondary voice say, I can understand, and I didn't go into it any further.
　It's probably because it's Nihonium, and it's because it's Nihonium that she knows that, and that's why she left the dungeon to come here, even though it's daytime.

　She also gave the dungeon master the ability of drop disappearance out of "will and refusal".
　I guess I understand those feelings.

　I'm convinced of that because I know the truth.
　The truth that Erislonium was killed just before.

　He was killed and born again, but that frightened me and I refused to allow humans to enter the dungeon.

　It was an obvious connection, and I was easily convinced.

'Although,'
Yeah?
'It's impossible to reject them outright. You can only get in if you meet some conditions, or at least that much.
Is that how it works?

　Nihonium nodded clearly.

'We can only enter one day a year. That's the most stringent requirement imaginable.'
I see.

　Can't even a spirit completely refuse entry to a human?
　Humans and dungeons - spirits.
　There's still a lot I don't know about the relationship between the two in this world, so I'm a little curious.

　I approached the entrance of the dungeon.

　If I can't get in, that's fine, but I've learned the inexcusable fact that Erislonium has been killed, and I hear a voice, though it may be empty, telling me to help.

　At the very least, I'd like to know the conditions of entry.

　With that in mind, I touched the invisible wall that Emily and Eve couldn't get through.

　I was struck by the unexpectedness of what I thought was there - not what I thought was there.

　My hand cut the sky so grandly that I could hear a "squawk" sound, and I almost fell to my knees.
　I took a step forward and stayed on.

'What?'

　I heard Emily's voice.
　I turned around and saw her surprised outside the dungeon (、、、、、、、).
　And I'm in the dungeon.

'I'm in: ......'
How did you do it?
No, come on in, Emily.
Hi. ...... I can't get in.
It's exactly the same as before.

　Emily couldn't get in after all, the walls were blocking me, and even with Emily's power, I couldn't move forward even a step.

　I made it out of the dungeon, I got out normally.
　I went in again, I got in normally.

　I went in and out, and in and out.
　I went in and out of the dungeon's entrance borders like a repetitive side jump.

　I could get in and out with no problem at all.

'Low level, cocky,'
Aha!

　Eve is a bit grumpy as she gives me the chop when I get outside.

　It's because I can't get in, but...

What?
What's going on?
Eve, what did you say?
'I demand an apology and a carrot from the low level'
At least blur the words you say!

　It was a big shove.
　But it was still good.

　The words Eve had said - low level.

　A familiar word I've heard hundreds of thousands of times since I met her.

　Low level - level one.

　Killed ...... frightened ...... rejected ...... low level.

'A level-restricted dungeon?'

　Erislonium admission restrictions.
　It was something that felt so fitting to say, that it was the only way it could be.
